Hydrocarbon-burner for stills



UNITED STATES PATENT FFICE.

ISAAC HELME, OF PHILADELPHIA, PENNSYLVANIA.

HYDROCARBON-BURNER FOR STILLS, ENGINES, 80C.

Specification forming part of Letters Patent No. 59,393, dated November6, 1866.

To all whom t may concern:

Beit known that l, ISAAC HELlvLE, of Philadelphia, in the county ofPhiladelphia, and in the State of Pennsylvania, have invented certainnew and useful Improvements in Hydrocarbon-Burners for Stills andEngines; and I do hereby declare that the following is a full, clear,and exact description thereof', reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Inthe annexed drawings, making part of this specification, A representsa metallic cup, cast with two flanges, d d, w-hieh project upward andform between them the receptacle for lthe burning-Huid. a t (t arepresent four arms. which are Cast with the cup A, running from theinner flange to the hub e, at the center of the said cup. There is nometal between the arms a a, as seen. B represent-s a metallic hoop,which .surrounds the cup A, heilig made of little larger diameter thanthe cup. This hoop is cast with a ange, which forms a top for it, saidflange or top being provided with an lannular openinglarge enough toleave about onehalf of the burning-huid receptacle uncovered by it. Thisange or top does not fit down close to the receptacle for uid, butstands a little above it. C represents a metallio disk, the diameter ofwhich is a little greater than the annular opening in the hoop B, orrather its rlange or top. D represents a stem, with a thread eut uponits lower end.

This stem passes into the opening in hub e.

By turning the stein D the disk C is raised and lowered, or broughtcloser to or removed from the iiange or top of the hoop B.

Steam may be passed through the stem D and into the frame throughperiphery of disk C, if hollow.-

Y In using this burner the fluid, whether coaloil or any other kind ofoil which it may be desirable to use, is conducted to the uidreceptaclebetween the flanges d d by means of a pipe from the tank containing' it.

The iiuid, when set on rire, produces a dame, which passes up around theedges ot' the top or han ge of hoop B, strikes the under side ot' thedisk C, and, being spread by it, passes up and around its edges to theboiler or still to be heated. v

It will be perceived that there will be a draft of air up through thecenter of cup A, and also up around its outside, between it and the hoopB.

The iiame can be made more or less in volume by raising or lowering thedisk U, and of course the degree of heat can be regulated in this way.

I do not propose to confine myself to any particular kind of oil, nor tothe shape of this burner, as it may be made oblong or of dilferentshape.

What I claim is- The cup A, the hoop B, and the disk C, provided With astem or its equivalent for adjustment, the several parts beingconstructed and arranged substantially as and for the purpose hereinspecified.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of October, 1866.

ISAAC HELM E.
